If you need Google sign-in, the usual choices are:

Best common options

  1. Firebase Authentication

    • Easiest if you want a fast setup
    • Built-in Google provider
    • Good for web, iOS, Android, and many backend setups
    • Nice if you also want email/password, phone auth, etc.

  2. Auth0

    • Good if you want a more full-featured auth platform
    • Supports Google and many other identity providers
    • Better for enterprise-style apps, SSO, advanced rules, and flexible login flows

  3. Google Identity Services directly

    • Best if you only need Google login and want less vendor dependency
    • You’ll handle more of the app/session logic yourself
    • Good for simple web apps

  4. NextAuth / Auth.js if you’re using Next.js

    • Easy Google OAuth integration
    • Great for web apps built with Next.js
    • You still manage your own session/database strategy

Quick recommendation

  • Simple app / fastest setup: Firebase Auth
  • Next.js app: Auth.js (NextAuth)
  • Need enterprise/advanced auth: Auth0
  • Only Google login, want control: Google Identity Services

If you tell me your stack, I can recommend the best one more specifically.
